Insecticides killing bees?

In the course of researching bugs on my plant (scale insects) i found a site that says certain insectacides contain chemicals that are killing off large numbers of bees:

does anyone have any views on this and are there any greener insecticides that i can use?

Neem oil (I've never tried it though)

snip:
Neem Oil Amounts For Insect Spray

For 1 liter of a 0.5 % dilution of neem plant spray you need:

• 5 ml neem oil
• 1-2 ml insecticidal soap or other detergent
• 1 liter warm water

Method For Preparing Neem Insect Spray

• Use warm water if possible. If making a large batch make a premix in a small amount of warm water, then add that into the big container.
• Mix the warm water with the soap first!
• Then slowly add the oil while stirring vigorously.
• Fill the mix into your sprayer.
• (Or fill the premix into your sprayer, which should already contain the rest of the water. Mix well.)
• Keep shaking or otherwise agitating the mix while spraying.
• Use the mixture within eight hours.

Additional Instructions

Spray the neem insecticide solution on all the leaves, especially the undersides where insects like to hide. If you have plenty drench the soil around the roots as well. It does not hurt, neem oil is actually good for your soil.
Use your neem insect spray as quickly as possible, definitely within eight hours. Once your batch neem garden spray is mixed the neem oil starts breaking down. Always make a fresh neem insecticide batch for spraying, and only prepare the amount you need.
How often should you use neem garden spray? The suggestions below are general guidelines. Keep a close eye on things and fine tune as needed. If you are worried about sensitive plants, spray just a little bit in a small area, wait for a day or two, and see what happens. If you use insecticidal soap you should not have any problems.
Neem plant spray as a preventative measure: Spray once a fortnight using a 0.5 % solution. This should prevent any insect problems in the first place.
Neem insect spray to fight an infestation: When spraying the first time throroughly drench al leaves and the soil around the plant. Then spray once a week until the problem disappears. If it rains you may need to respray sooner. If you are dealing with a less sensitive insect species you may need to increase the concentration of the neem spray. See how you go.

Didn't know about them killing bees, not that I use them.

 

Well, I'm no scientist but insecticides are made to kill insects. Bees are insects. Ergo insecticides kill bees.

 

thats old science .... new science will make 'genetically modified bees'

Well insecticides are insecticides and they are made to kill insects. Bees are a kind of good skadedyr (insect) that nobody wants to lose in a pesticide spray. Neem oil looks like a workable solution but still not sure about it. Please consult a registered pest controller firm to help you better.
